CUFF-PIN.

Specification of Letters Patent.

Patented Jan. 4, 1910.

Application filed November 5, 1908. Serial No. 461,187.

To all whom it may concern:

Be it known that I, FRANK E. FARNHAM, a citizen of the United States,residing at Providence, in the county of Providence and State of RhodeIsland, have invented certain new and useful Improvements in Cuff- Iins,of which the following is a specification, reference being had thereinto the accompanying drawings.

Like reference numerals parts.

Figure 1 is an inverted plan view of the cupped shell or ornamental bodyof my improved cuff pin. Fig. 2 is a side elevation of the same. Fig. 3is a plan view of the lining plate. Fig. 4 is a plan view of the blankfrom which my improved pin catch is made. Fig. 5 is a sectional view ofthe finnished pin catch after said blank has been formed and bent, thesection being on line a a of Fig. 4. Fig. 6 is a plan view of saidlining plate after the pin catch has been mounted thereon. Fig. 7 is asectional view of the parts as seen on line b b of Fig. 6. Fig. 8 is aplan view of said lining plate laid loosely in the concavity of theshell or body portion of the cuff pin as seen before the flange of saidshell or body has been rolled over upon the lining plate. Fig. 9 is asectional view of the parts as seen on line 0 c of Fig. 8. Fig. 10 is aplan view of the lining plate having the pin catch in position thereonand of said shell or body portion with the flanges thereof rolled overinto contact with the lining plate. Fig. 11 is a sectional view of theparts as seen on line (Z cl of Fig. 10. Fig. 12 is a view of my improvedcuff pin as seen in central longitudinal section. Figs. 13 and 14represent modified forms of securing the pin-catch end of the liningplate in the shell or body portion.

My invention relates to the class of cuff pins or brooches, -andparticularly to an improved slidable pin catch therefor; and it consistsof the novel construction and combination of the several parts hereindescribed and claimed.

In the drawings the reference numeral 1 designates an ornamental shellor front portion of a cufi pin or brooch. It is preferably made ofgold-plated metal. In cross section it is concavo-convex, or of anypreferred form, and is provided with the two opposite side flanges 2, 2,and with the two short projections 3, 4, at the pointed ends thereof.

indicate like In Figs. 2 and 8 the ends 3, 4, are shown as bentupwardly.

A lining plate is shown at 5 and is of a form and size to enable it tobe laid loosely in the concavity of the ornamental shell or body portion1 of the cuff pin. The usual air-holes or semicircular notches 6, 6, arecut on the edges of said plate, and there are also formed the twoopposite small shoulders or stops 7 7. The pointed end 8 of the plate 5is somewhat reduced in width as illustrated in Fig. 3. The lining plate5 is provided wlth two ear pieces or pin joints 9, 9, opposite eachother, and located near the pointed end 10 of the plate. These earpieces are preferably integral with the plate 5. The ear pieces or pinjoints 9 have the pivot holes 11; or any other known kind of pin jointsmay be used, which is adaptable for the purpose.

My improved pin catch 12 is made from thin sheet metal. A blank 13 iscut from such a sheet in the form illustrated in Fig. 4, The two ends 14are rectangular, the central portion is convexed on the one edge asshown at 15, and the metal connecting said central portion with the ends14 is U-shaped as seen at 16. The ends 14 of the blank 13 are to be benttransversely on the lines 17, 18, to form a groove 19, and the blank 13is also to be bent transversely at 20 into a U-shape. There is thusformed a hooded pin catch, with its lower ends or bases 21 separated onefrom the other and leaving there a longitudinal space or channel 22.These bases 21, 21, fit slidingly along the pointed end 8 of the liningplate 5 until they come into abutment with the shoulders or stops 7, 7,of said plate, hen the pin catch 12 has been so mounted and located onthe lining plate 5, said lining plate is laid loosely in the concavityof the shell or body portion 1 of the cufl pin, and the tips orprojections 3 and 4 are bent down into contact with the ends-10 and 8,respectively, of the lining plate 5, as shown at 3 and 4 in Fig. 10. Theside flanges 2, 2, are rolled over by a suitable tool into contact withthe lining plate 5, as illustrated at 2 2 in Figs. 10, 11 and 12.

A pin tongue 23 has a pivot 24, which is mounted in the pivot holes 11of the ear pieces or pin joints 9, as seen in Fig. 12, the said earpieces or ear joints 9 being bent up to lie parallel, one with theother, in contact with the head of the pin 23 on both sides thereof,respectively; or any other suitable pin may be used as preferred. I thusdispense with the use of solder in fastening the pin catch to the liningplate. The pin catch 12 is held upon the lining plate 5 by being slidthereon along the pointed end 8 'of said plate until it abuts theshoulders 7, 7. The lining plate 5 is then fastened in position by thebent projections 3, as, and. by the rolled-over flanges 2. This separateand detachably mounted pin catch is a new article of manufacture, andconstitutes a jewelers finding, and is salable in quantities to jewelersfor use in their own construction of cuff pins and brooches. As thepointed end 8 of the lining plate is somewhat tapering in form, as seenin Fig. 3, the bases 21 of the pin catch 12 are somewhat sprung or putunder tension when they are moved into abutment with the shoulders 7,and when mounted as represented in Fig. 3 are held in position upon thelining plate in whole or in part by spring-pressure.

Instead of bending the blank (Fig. at) on the lines 17, 18, asdescribed, the sheet metal strip, from which the pin catch 12 is formed,may be made with two parallel longitudinal grooves 19 and the pin catch12 be cut from such grooved stock. Instead of confining the pin-catchend of the lining plate 5 in position within the shell or body portion 1simply by the bent-over end or projection a the flanges 2 of said shell.or body portion may be made longer than is shown in Fi 2, so as toextend along the external portion of the bases of the pin catch and berolled over thereon as illustrated at 2 in Fig. 13. So also the flange 2may be continuous around the pin-catch end of said lining plate andturned over continuously into contact therewith, as shown at 2 in Fig.14, to overlie the projection or end l, or said end a, 4; may beomitted.

It is obvious that my improved pin catch can be used in connection withother articles of jewelry besides cuff pins and brooches, but such otheruse is within the scope of my patent.

I claim as a novel and useful invention and desire to secure by LettersPatent 1. I11 av cuff pin, the combination of a lining plate; a pincatch having a resilient base by which it is mounted upon and engageablewith the lining plate and is secured in position thereon by saidresilient base.
